International "false friends"

In Italian and Portuguese, the word nefrite means both "nephrite" and "nephritis". In French, the word néphrite equally means "nephritis". If nobody disagrees, to avoid international visitors to look for one word and find something else (it happened to me, I'm Italian) I would modify the "other uses" header to include: "For the kidney inflammation, see Nephritis."

Made it even better [1]. Does the article Nephritis also need a hatnote? Lord Sesshomaru (talk • edits) 20:21, 30 December 2008 (UTC)[reply]

Image of finished gem needed

We need a picture of a polished piece of nephrite. Even the two rough examples in the article aren't very good. --208.65.188.23 (talk) 04:05, 4 March 2009 (UTC)[reply]

Chemistry Required

We need to include why different colors exist for nephrite when the chemical composition is the same: so it is they way it is made that makes it present different colors? This needs to be explained.Curb Chain (talk) 11:52, 10 June 2011 (UTC)[reply]

Nephrite is variably colored because the tremolite - ferro–actinolite solid solution series varies from white to light green for Ca-Mg tremolite to deep green for iron rich Ca-Fe ferro-actinolite. Would need to find a ref to support my off the top of me head stuff and it appears we need an article for ferro-actinolite to zap the red link above. Vsmith (talk) 14:49, 10 June 2011 (UTC)[reply]

Better pictures

We should have a rough jade image & a polish jade image and a craved jade image from china and another nation which is famous for it's jade.

page seems abit dull without a beautiful carving showing its true finished result82.38.161.217 (talk) 20:31, 8 January 2014 (UTC)veda[reply]

"Mutton fat"

...jade is mentioned here and elsewhere in jade articles but no description or reason is given for this interesting name, mutton fat. Anyone know??? Buster Seven Talk 12:14, 17 June 2016 (UTC)[reply]

Seems clear from the images in the article. - Rod57 (talk) 11:33, 5 April 2022 (UTC)[reply]

Needs some simplified commercial data

What countries produced the most, year-by-year, for the past 10 years. Or even a summary comparison with 20 and 50 years ago would be nice. What is the total amount for each of those top 10 countries, per year? Where is the world's biggest mine still in production? What is the wholesale price per gram or kilo (unprocessed)? This article needs data like that.Starhistory22 (talk) 23:09, 4 September 2017 (UTC)[reply]

Toughness

Although of modest hardness, apparently some Jade is very tough - resistant to fracture on impact. - Rod57 (talk) 11:35, 5 April 2022 (UTC)[reply]
